根据题目的条件或要求设计出合理的电路,是初中物理的一个重点与难点问题.解决这类问题时一定要抓住外部连接情况及对应现象,逐步画出可能的电路结构,最后综合考虑找到满足题中所有现象的电路,得出符合题意的答案.教师在电路设计教学中要善于教会学生掌握好电路设计的方法与技巧,让学生轻松学好电路设计.本文结合相关生活应用实例对电路设计的方法与技巧进行逐一介绍,与同仁一起分享和交流.一、每种情况画1条支路,各种情况都要用到的元件画在
According to the conditions or requirements of the design of a reasonable circuit, is a junior high school physics a focal point and difficult problems.To solve these problems must grasp the external connection and the corresponding phenomenon, and gradually draw the possible circuit structure, and finally consider Satisfy the problem of all the phenomena of the circuit, come up with the answers to the questions.Teachers in circuit design teaching should be good at teaching students to master the circuit design methods and techniques, so that students can easily learn the circuit design.This article combines the practical examples of life on the circuit Design methods and techniques introduced one by one, and colleagues to share and exchange. First, draw a branch in each case, the elements used in various situations are drawn
